It is recommended that you build PDO as a shared extension, as this will allow you to take advantage of updates that are made available via PECL. The recommended configure line for building PHP with PDO support should enable zlib support (for the pecl installer) as well. You may also need to enable the PDO driver for your database of choice; consult the documentation for <a href="pdo.drivers.html" class="link">database-specific PDO drivers</a> to find out more about that, but note that if you build PDO as a shared extension, you must build the PDO drivers as shared extensions. SQLite extension depends on PDO so if PDO is built as a shared extension, SQLite needs to be built the same way. <div class="example-contents"><pre><div class="cdata"><pre>./configure --with-zlib --enable-pdo=shared --with-pdo-sqlite=shared --with-sqlite=shared</pre></div> </pre></div> </p> </li> <li> <p class="para"> After installing PDO as a shared module, you must edit your php.ini file so that the PDO extension will be loaded automatically when PHP runs. You will also need to enable any database specific drivers there too; make sure that they are listed after the pdo.so line, as PDO must be initialized before the database-specific extensions can be loaded. If you built PDO and the database-specific extensions statically, you can skip this step. <div class="example-contents"><pre><div class="cdata"><pre>extension=pdo.so</pre></div> </pre></div> </p> </li> <li> <p class="para"> Having PDO as a shared module will allow you to run <strong class="command">pecl upgrade pdo</strong> as new versions of PDO are published, without forcing you to rebuild the whole of PHP. Note that if you do this, you also need to upgrade your database specific PDO drivers at the same time. </p> </li> </ol></div> <div class="procedure"> <b class="title">PHP 5.0.0 and up on Unix systems</b> <ol type="1"><li> <p class="para"> PDO is available as a PECL extension from <a href="http://pecl.php.net/package/pdo" class="link external">» http://pecl.php.net/package/pdo</a>. Installation can be performed via the <strong class="command">pecl</strong> tool; this is enabled by default when you configure PHP. You should ensure that PHP was configured --with-zlib in order for <strong class="command">pecl</strong> to be able to handle the compressed package files. </p> </li> <li> <p class="para"> Run the following command to download, build, and install the latest stable version of PDO: <div class="example-contents"><pre><div class="cdata"><pre>pecl install pdo</pre></div> </pre></div> </p> </li> <li> <p class="para"> The <strong class="command">pecl</strong> command automatically installs the PDO module into your PHP extensions directory.
